CONSTANT VOLTAGE REGULATORS & POWER LINE CONDITIONERS
Acme® True-Power® Power Line Conditioners
The average computer installation, representing mini-computer,
workstations or personal computers, experiences an average of
100 power disturbances each month. These disturbances can
cause equipment malfunction, loss of memory and inaccurate
data, and in the worst cases complete failure of these delicate
electronic devices. Computer installation manuals recommend
dedicated service lines, but these are expensive to install, offer
minimal future flexibility and do not provide total protection of
the equipment. Acme offers a complete line of Power Protection
Equipment. Refer to the “Product Selection Guide” for the product
that best meets your requirements.
Note: This section of the general catalog contains complete
specification and selection information on Acme’s True-Power
power line conditioners.
Acme True-Power® products consist of speciality designed ferroresonant transformers. Although ferroresonant transformers have
been an economical solution to power problems for many years, it
took the skills of Acme’s highly regarded engineering staff to refine
it to meet today’s exacting requirements.
For example, typical ferroresonant transformers have an input
limited to 100-130 V. Acme’s True-Power
range of +10/-20% around input voltage nominals of 120/208/240
and 480 volts. At 120 volt input, this relates to 95-130 volts.
The typical ferroresonant transformer has limited electrical noise
suppression capability. True-Power
the following noise attenuation capability:
®
Common Mode: 120 db
Transverse Mode: 60 db
The typical ferroresonant transformer has an audible hum that

can be objectionable in most offices. Acme’s True-Power
line conditioners are encapsulated in epoxy to lower sound levels
below ANSI standard C 89.2.
The typical ferroresonant transformer has on output regulation
of ± 3% for input line changes only. Acme’s True-Power
line conditioners have an output regulation of ± 3% for input line
and load changes, making them suitable for operation at any load
condition.
FEATURES
■
Reliable, regulated output voltage when input voltage varies,
even to brownout levels.
■
Extended operation to 65% of nominal when operated at 60% of
full load.
■
Noise rejection—effectively suppressing transient spikes and
surges—120 db common mode and 60 db transverse mode.
■
Rapid response to line and load changes—5% variation in 8m
sec, 10% variation in 16m sec.
■
Hold up time of 3m sec for complete loss of input power.
